2496aac3bc147e47b4fa91a8b4af34618dd2518e Temporary workaround for KUDU-1959 (race when selecting rowsets)
As described in the JIRA, there is a race by which multiple MM threads
can race to pick the same rowsets for compaction. Rather than crash when
hitting this bug, it is safe to simply abort that compaction attempt.
The MM will warn about the compaction failure and try again.
This is a temporary workround for the 1.4 release since the issue was
recently reported in the wild on the user list.
